Title: Tibial resector guide
Inventor: JOHNSON TODD S
IPC: A61B17/14
Filed: 1992-11-19
Abstract: A tibial resector guide having an angularly adjustable head controlled by a thumb actuated slide mechanism. The head may be positioned in a plurality of predetermined angular orientations in the anterior-posterior plane. The cutting head guide includes angled side walls which permit the guide to have a narrow aperture yet allow the saw blade to completely, pass through the tibia.  Further, the tibial resector of this invention includes a telescoping rod and a length adjustment mechanism adjacent the head for providing small height adjustments for positioning the head.      The length adjustment member includes an enlarged thumb wheel to ease operation. A pinning platform is connected to the adjustment member such that it is shiftable with the adjustment member relative to the guide head. The pinning platform permits the surgeon to pin the upper end of the instrument to the patient's leg preventing movement of the instrument during resection. After pinning, the head may be further adjusted in height by rotating the adjustment member. The instrument further includes a sliding ankle adjustment to provide proper alignment of the guide with the tibia and femur.

Abstract: BIOMETRIC TOKEN FOR AUTHORIZING ACCESS TO A HOST SYSTEM              ABSTRACT OF THE DISCLOSURE           A security apparatus receives a biometric input from a user, which then is compared to a template to determine a correlation factor.  The correlation factor, a fixed code and either a time-varying code or a challenge code then are combined to generate a token. The token is displayed to the user, who then  enters the token at an access device.  The access device is coupled to a secure host system.  The access device forwards the token to the host, which processes the token to determine whether access is permitted.  In one embodiment, the host is an electronic banking system.  If access to such system is permitted the user is allowed to perform an electronic funds transfer.  The security apparatus in one embodiment is an integrated circuit card.  Each apparatus includes a sensor for detecting the holder's biometric information (i.e., voice, signature, fingerprint), along with a processor and display. The processor generates the token which then is displayed to the holder.

Filed: 1993-03-31
Abstract: ABSTRACT OF THE DISCLOSURE      When a mixture of spent electric batteries is treated by pyrolysis, a pyrolysis slag is obtained having at least a residual mercury content between 50 and 1500 ppm, according to the battery type.  It does not seem possible to eliminate this residual content by simply modifying the parameters of this pyrolysis process.  The residual content may however be lowered below 10 ppm by a second thermal treatment between 500 °C and 700 °C.  Preferably the material to be treated is crushed between the first pyrolysis and the second thermal treatment, and the second thermal treatment is carried out while air or nitrogen is blown through the material.
Patent CA-2114260-A1 (CA)
Inventor: PETERSON BERNARD L
IPC: B26D5/38
Filed: 1994-01-26
Abstract: A powered bread slicer capable of slicing successive loaves of bread to selected different slice thicknesses.  A rotating circular bread slicing knife is mounted on a pivotal, reciprocal arm for shifting the knife from a retracted position through slicing positions between and transverse to an infeed table and an outfeed table, and return to the retracted position.  The slice thickness is selected, as for standard one-half inch thickness, deli one-quarter to three-eighths inch thickness, garlic or French bread up to one inch thickness, or otherwise.  A variable stepper motor incrementally advances a loaf pusher one step at a time, the dimension of the step being of the selected slice thickness dimension.  The distance by the travelled loaf pusher to reach the end of its travel is monitored to determine whether the bread heal is thick enough to slice once more.  This decision is a function of the selected slice thickness dimension.  A detector sensing the leading end of the loaf initially activates the slicer knife drive and the support arm drive.  A pusher detector adjacent the knife prevents knife advancement with presence of the pusher adjacent the knife, allowing the pusher to move past the knife to push the fully sliced loaf completely onto the discharge table, and then return to the infeed table.
